Suppose f (x,y) = x y , P = (1,−4) and v = −2i+4j. A. Find the gradient of f. Ñf = i+ j Note: Your answers should be expressions of x and y; e.g. “3x - 4y” B. Find the gradient of f at the point P. (Ñf ) (P) = i+ j Note: Your answers should be numbers C. Find the directional derivative of f at P in the direction of v. Du f = Note: Your answer should be a number D. Find the maximum rate of change of f at P. Note: Your answer should be a number E. Find the (unit) direction vector in which the maximum rate of change occurs at P. u = i+ j Note: Your answers should be numbers Answer(s) submitted: •
